    Abstract: A variation of expanding solvent steam assisted gravity drainage (ES-SAGD) production of heavy oil wherein steam and hydrocarbon solvent are co-injected into a heavy oil reservoir and water, hydrocarbon solvent and heavy oil are produced by gravity drainage until the steam chamber is well developed or until oil recovery reaches about 20-30% of oil in place. At that time, the wells are switched to a lateral sweep using non-condensible gas (NSG) and steam co-injection, where more hydrocarbon solvent is recovered than is recovered with ES-SAGD used alone and where the cumulative steam to oil ratio is reduced over using -ES-SAGD alone.

  • Patent number: 10408032
    Abstract: A system and method of producing a deposit of gas and liquid hydrocarbons from a subterranean formation, where a pressure of the gas hydrocarbons is regulated. Strategically regulating a pressure of the gas hydrocarbons prevents the gas hydrocarbons from expanding into a path of the liquid hydrocarbons flowing to a wellbore. The liquid hydrocarbons are produced through a production well that is drilled from surface and into a zone within the subterranean formation containing the deposit. A gas expansion circuit is also drilled through the formation, and has a portion that terminates proximate an interface between the gas and liquid hydrocarbons. Thus as the gas hydrocarbons expand into spaces left empty by draining the liquid hydrocarbons, the expanding gas is diverted into the gas expansion circuit rather than into the path of liquid hydrocarbons still in the zone. The gas expansion circuit can have a “fish-bone” configuration.

  • Patent number: 8985205
    Abstract: An in situ extraction process for heavy oil reservoirs using solvent comprises removing liquids and gases from areas contacting with the heavy oils to increase an interfacial area of unextracted heavy oil contactable by the solvent. Solvent vapor is injected into the areas to raise the reservoir pressure until sufficient liquid solvent is present to contact the increased interfacial area. The reservoir is shut in for a sufficient time for the solvent to diffuse into the unextracted oil across the interfacial area in a ripening step to create a reduced viscosity blend of solvent and oil. One or more reservoir characteristics is measured to confirm the extent of solvent dilution that has occurred of the unextracted oil in the reservoir. Gravity drainage based production is commenced from the reservoir upon the blend having a viscosity low enough to permit the blend to drain through the reservoir to a production well.

  • Publication number: 20150013978
    Abstract: An inflow control valve for controlling the flow of fluids into a generally horizontal production well located in an underground reservoir, where the production well has a well casing, a production tubing located within the casing and an annulus between the production tubing and the casing. The inflow control valve has a valve body having a threaded portion for connecting the valve body to the production tubing, a through bore for connecting the valve body to an inside bore of said production tubing and an outside surface. The valve also has at least one inlet passageway extending through the valve body between the outside surface and said through bore and an inlet opening on said at least one inlet passageway formed on the outside surface of the valve body.

  • Publication number: 20150013977
    Abstract: The present invention relates to systems, apparatuses, and methods for providing a reliable, high purity source of CO2 that is used in the recovery of formation deposits, such as fossil fuels. At least a portion of the fossil fuels recovered may be directly combusted or extracted using the same process used to provide the pure source of CO2 without the need to first remove CO2, sulfur, other fossil fuels, or other impurities.

  • Patent number: 8919445
    Abstract: Method of managing hydrates in a subsea production system that includes a host production facility, one or more producers, one or more water injectors, a water injection line, and a single production line for directing production fluids from the producers to the host production facility. The method comprises placing a pig in the subsea production system, shutting in production from the producers, and injecting a displacement fluid into the subsea production system in order to displace production fluids in the production line. The method also includes applying electrically resistive heat along a selected portion of the single production line to maintain production fluids within the production line at a temperature above a hydrate formation temperature after production has been shut in.

  • Publication number: 20140352958
    Abstract: A process for recovering oil from an oil-bearing formation is provided. A first oil recovery fluid is introduced into a formation through a first well for a first time period and oil is produced from a second well. A second oil recovery fluid different from the first oil recovery fluid is introduced into the formation through the second well for a second time period after the first time period, and oil is produced from a third well, where the second well is located on a fluid flow path extending between the first and third wells.

  • Patent number: 8893787
    Abstract: Casing valves for selective well stimulation and control. A well system includes at least one valve interconnected in a casing string operable via at least one line external to the casing string to selectively control fluid flow between an exterior and interior of the casing string, and the casing string, valve and line being cemented in a wellbore. A method of selectively stimulating a subterranean formation includes: positioning a casing string in a wellbore, the casing string including spaced apart valves operable via a line to selectively control fluid flow between an interior and exterior of the casing string; and for each of multiple intervals of the formation in sequence, stimulating the interval by opening a corresponding one of the valves, closing the remainder of the valves, and flowing a stimulation fluid from the casing string into the interval.
